Given numbers are 738, 102, 639, 455
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(738, 102) = 12546
GCD(738, 102) = ( 738 x 102 ) / 12546
= 738 / 102
= 738
Step2:
LCM(6, 639) = 1278
GCD(6, 639) = ( 6 x 639 ) / 1278
= 6 / 639
= 6
Step3:
LCM(3, 455) = 1365
GCD(3, 455) = ( 3 x 455 ) / 1365
= 3 / 455
= 3
So, Greatest Common Divisor of 738, 102, 639, 455 is 1
